Answer :
Answer:
Correct answer: (x + 1)² + (y - 3)² = 4
Step-by-step explanation:
Given:
x² + 2 x + y² - 6 y = - 6
I suppose your question should have been to:
Write the standard form of the circle equation
First, we will form a complete square of the binomial for both variables.
x² + 2 x + 1² - 1² + y² - 2 y 3 + 3² - 3² = - 6
(x + 1)² + (y - 3)² - 1 - 9 = - 6
(x + 1)² + (y - 3)² = 10 - 6
(x + 1)² + (y - 3)² = 4
This is the standard form of the circle equation
God is with you!!!
